Treatment of biodiesel wastewater using ferric chloride and ferric sulfate [PDF]

open access: yes, 2017
The production of biodiesel through the transesterification method produces a large amount of wastewater that contains high level of chemical oxygen demand (COD) and oil and grease. In this study, coagulation was adopted to treat the biodiesel wastewater.

Terrain Classification for Planetary Rovers Using Wireless In‐Wheel Sensor Modules and Machine Learning

open access: yesJournal of Field Robotics, Volume 43, Issue 3, Page 1884-1904, May 2026.
ABSTRACT Safe and reliable mobility over different kinds of ground is important for planetary rovers on space missions. Since terrain changes might affect the mobility of the rover, energy consumption, and safety, detecting the type of ground in real‐time is vital.

Software to Support Remote Sensing of River Discharge Based on Critical Flow Theory

open access: yesRiver Research and Applications, Volume 42, Issue 4, Page 915-928, May 2026.
ABSTRACT Water resource management requires accurate observations of streamflow but standard field methods for measuring river discharge ( Q ) can be costly and hazardous for equipment and personnel. Remote sensing has become a viable alternative, but many image‐based techniques require field data for calibration, and depth and velocity can seldom be ...

Three dimensional analysis of the exhalation flow in the proximity of the mouth

open access: yesHeliyon
The human exhalation flow is characterized in this work from the three-dimensional velocimetry results obtained by using the stereo particle image velocimetry (SPIV) measurement technique on the flow emitted from a realistic airway model.

Photodegradable Hydrogels for On‐Demand Modeling of Age‐Related Spatiotemporal ECM Deformation

open access: yesSmall, Volume 22, Issue 27, 14 May 2026.
A light‐tunable PEG hydrogel enables on‐demand, spatiotemporal modeling of drusen‐like ECM bulges in the aging outer retina. By precisely controlling bulge size, the platform reveals how retinal pigment epithelium morphology adapts to topographical changes without disrupting actin cytoskeleton or polarity, effectively mimicking early ageing before ...

Impacts of Blade Camber on Cross‐Flow Turbine Performance and Loading

open access: yesWind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT Cross‐flow turbines show promise for renewable energy generation from wind and tidal sources. The rotating reference frame of cross‐flow turbine blades results in virtual camber and incidence due to streamline curvature, altering the lift, drag, and pitching moment of the blades. Adding geometric camber is therefore likely to alter performance

A Novel Polynomial Approach for Particle Image Velocimetry (PIV) Image Reconstruction

open access: yesFluids
Particle Image Velocimetry (PIV) often utilizes a cross-correlation method to determine how far particles have moved between two captured images. The most common methods for vector estimation use computationally exhaustive cross-correlation functions ...

MEASUREMENT OF INUNDATING FLOW FROM A BROKEN ENBANKMENT BY USING VIDEO IMAGES SHOOT FROM A MEDIA HELICOPTER

open access: yesE3S Web of Conferences, 2018
The heavy rain disaster in the Kinugawa River basin that occurred along with the passage of the Typhoon 18 caused the embankment destruction in the middle reach of the river on September 10, 2015.
